C8300

different-operator-varname-taskid

For consistency assign the same variable name and task_id to operators.

C8301

match-callable-taskid

For consistency name the callable function ‘_[task_id]’, e.g. PythonOperator(task_id=’mytask’, python_callable=_mytask).

C8302

mixed-dependency-directions

For consistency don’t mix directions in a single statement, instead split over multiple statements.

C8303

task-no-dependencies

Sometimes a task without any dependency is desired, however often it is the result of a forgotten dependency.

C8304

task-context-argname

Indicate you expect Airflow task context variables in the **kwargs argument by renaming to **context.

C8305

task-context-separate-arg

To avoid unpacking kwargs from the Airflow task context in a function, you can set the needed variables as arguments in the function.

C8306

match-dagid-filename

For consistency match the DAG filename with the dag_id.

R8300

unused-xcom

Return values from a python_callable function or execute() method are automatically pushed as XCom.

W8300

basehook-top-level

Airflow executes DAG scripts periodically and anything at the top level of a script is executed. Therefore, move BaseHook calls into functions/hooks/operators.

E8300

duplicate-dag-name

DAG name should be unique.

E8301

duplicate-task-name

Task name within a DAG should be unique.

E8302

duplicate-dependency

Task dependencies can be defined only once.

E8303

dag-with-cycles

A DAG is acyclic and cannot contain cycles.

E8304

task-no-dag

A task must know a DAG instance to run.
